A2P 10DLC refers to a system in the United States that allows businesses to send Application-to-Person (A2P) type messaging via standard 10-digit long code (10DLC) phone numbers. Carriers in the US consider all business traffic to be A2P. Carriers’ A2P 10DLC offerings provide better delivery quality and lower filtering risk than long code SMS of the past, using the same phone numbers.

Direct Customers sending fewer than 3,000 messages per day to the US and using 5 or fewer long code numbers do not need to take any action.

What do you need to do?

If you do not send any messages to users in the United States using long code numbers, you do not need to do anything.

If you send messages to the US using your own brand (Direct Customers), but you always send fewer than 3,000 messages per day to the US using 5 or fewer long code phone numbers, you do not need to do anything at this time.

If you send more than 3,000 messages per day or use more than 5 long code numbers for messaging to the US, you must complete registration. A2P 10DLC registration can be done inside your YetiText account.

Brand Types and Fees

For brands sending more than 3,000 messages per day, you will be set up as a STANDARD BRAND. This brand type does come with a fee of $44 to register (don't worry, the benefits far outweigh the cost of the fee). For Brands sending under 3,000 per day you will be registered as a STARTER BRAND which does not currently have a registration fee associated with it.

How does A2P 10DLC work?

There are two important requirements under the new A2P 10DLC system:

  1. Businesses must identify who they are to the carrier networks (Brand registration).

  2. Businesses must register what type of messages they are sending, i.e. notifications (Campaign registration).

What happens if I don't register?

If your message volume requires you to register (see the thresholds described above) and you have not completed registration by October 1, 2021, your message traffic may be subject to heavier carrier filtering. Increased per-message carrier fees may apply to unregistered traffic after this date.

How does US A2P Brand registration work?

When you complete your US A2P Brand registration, your Brand will receive a Trust Score from 0 to 100. This rating influences the maximum message throughput that will be allocated to each of your Campaign use cases.

What is a Trust Score, and how does it affect me?

When you complete the registration of your Brand and Campaign(s) for A2P Messaging through your YetiText account (if required), that information is sent from YetiText to The Campaign Registry (TCR), a 3rd party at the center of this new registration system. YetiText also automatically submits your Brand for secondary vetting, which uses a reputation algorithm to review specific criteria relating to your company, and assign a Trust Score that will determine your messaging throughput and T-Mobile daily message limits.

How do Trust Scores influence message throughput?

Trust Scores are grouped into three levels, from lowest to highest. Your Trust Score level, combined with your Campaign Type, will determine the message throughput that is allocated to your campaign use case.

What’s a campaign use case?

This represents a messaging use case, for example, sending account notifications or conducting marketing.

Some companies may only need to register one campaign use case, in other scenarios you may have multiple. For example, if you are a company that sends authentication codes to validate new users, but you also send marketing messages, you should register two campaign use cases.

Do I need to buy new phone numbers to use this A2P 10DLC service?

If you are already using long code numbers, there is no need to buy new numbers. You will enable your existing numbers to use the new A2P 10DLC service by following the registration process.

Is messaging to Canada or any other countries also affected by these changes?

No. Canadian mobile carriers may introduce registered A2P 10DLC solutions in the future, but at this time carriers have not announced any plans to do so.
